Pleistocene glacial and interglacial ecosystems inferred from ancient DNA analyses of permafrost sediments from Batagay megaslump, East Siberia

open access: yesEnvironmental DNA, Volume 4, Issue 6, Page 1265-1283, November 2022., 2022
As the past is the key to the future, to understand community transformations and ecological interactions, we reconstructed ecosystem‐wide biotic composition (from viruses to megaherbivores) between glacials and interglacials from the Middle and Late Pleistocene at the Batagay megaslump, east Siberia.

Exposure to Mimivirus collagen promotes arthritis [PDF]

open access: yes, 2014
Collagens, the most abundant proteins in animals, also occur in some recently described nucleocytoplasmic large DNA viruses such as Mimiviridae, which replicate in amoebae.

Isolation and complete genome sequencing of Mimivirus bombay, a Giant Virus in sewage of Mumbai, India

open access: yesGenomics Data, 2016
We report the isolation and complete genome sequencing of a new Mimiviridae family member, infecting Acanthamoeba castellanii, from sewage in Mumbai, India. The isolated virus has a particle size of about 435 nm and a 1,182,200-bp genome.

A pelagic microbiome (viruses to protists) from a small cup of seawater [PDF]

open access: yes, 2017
The aquatic microbiome is composed of a multi-phylotype community of microbes, ranging from the numerically dominant viruses to the phylogenetically diverse unicellular phytoplankton.

Virophages Found in Viromes from Lake Baikal

open access: yesBiomolecules, 2023
In this study, a previously little-studied group of viruses—virophages—was searched for and identified in the viromes of the ancient oligotrophic Lake Baikal.

Exploring Viral Diversity in a Unique South African Soil Habitat [PDF]

open access: yes, 2018
The Kogelberg Biosphere Reserve in the Cape Floral Kingdom in South Africa is known for its unique plant biodiversity. The potential presence of unique microbial and viral biodiversity associated with this unique plant biodiversity led us to explore the ...

High-level diversity of tailed phages, eukaryote-associated viruses, and virophage-like elements in the metaviromes of Antarctic soils [PDF]

open access: yes, 2014
The metaviromes of two distinct Antarctic hyperarid desert soil communities have been characterized. Hypolithic communities, cyanobacterium-dominated assemblages situated on the ventral surfaces of quartz pebbles embedded in the desert pavement, showed

Genomic comparison of closely related Giant Viruses supports an accordion-like model of evolution.

open access: yesFrontiers in Microbiology, 2015
Genome gigantism occurs so far in Phycodnaviridae and Mimiviridae (order Megavirales). Origin and evolution of these Giant Viruses (GVs) remain open questions.

Internal Nitrogen Pools Shape the Infection of Aureococcus anophagefferens CCMP 1984 by a Giant Virus

open access: yesFrontiers in Microbiology, 2020
The pelagophyte Aureococcus anophagefferens blooms annually in shallow bays around the world, where it is hypothesized to outcompete other phytoplankton in part by using alternative nitrogen sources.

GIANT VIRUSES: ORIGIN, SPREADING, TAXONOMICAL, STRUCTURAL-MORPHOLOGICAL AND MOLECULAR-BIOLOGICAL CHARACTERISTICS

open access: yesВопросы вирусологии, 2018
The brief review is devoted to description of the discovery of giant viruses belonging to the families of Mimiviridae and Marseilleviridae, as well as unassigned genera Pithoviruses, Pandoravirus, and Molliviruses.
